SANDY SPRINGS, Ga. -- No one was hurt in an hours-long SWAT standoff in Sandy Springs overnight.

The situation began at around 10 p.m. Wednesday when the suspect's mother called police to report that her son, Edward Quenzer, was acting erratic.

After the mother called police, Quenzer threatened her with a Taser-type stun gun, according to Sandy Springs Police spokesman Ron Momon.

North Metro SWAT and Sandy Springs Police officials responded to Quenzer's house on Old Woodbine Road and tried to negotiate with him.

Early Thursday morning, a SWAT team was able to get into the house and take Quenzer into custody without incident, Momon said. Quenzer will now undergo a mental evaluation at Grady Memorial Hospital; the suspect's mother said he has been displaying symptoms of paranoia and schizophrenia.

Police evacuated several of Quenzer's neighbors during the SWAT standoff, but no one was harmed.

(WXIA) -- A federal grand jury has indicted 17 members of a massive Mexican drug ring.

The defendants are accused of smuggling cocaine, heroin and methamphetamine to Georgia. Prosecutors said they also conspired to deliver a significant amount of drug money to Mexico.

According to information presented in federal court, Atenogenes Alvarado-Delgado runs the trafficking organization. His ring -- which includes his brother, Jose Alvarado-Delgado, and two associates -- used passenger buses to transport drugs from Mexico to the Atlanta area. Others would then unload the drugs and sell them in Georgia and Florida.

Since last October, law enforcement has seized much of the ring's wares in several busts, including:

* Oct. 8, 2013: 39 pounds of methamphetamine during a traffic stop in Doraville

* Oct. 11, 2013: 165 pounds of methamphetamine during a search of an apartment on Cleburne Parkway in Hiram
